Lessons learnt in Switzerland
–
17 million of certified MINERGIE
®
-Buildings have a
value of 50 billion CHF and 7 million m
2
total surface
of buildings in MINERGIE-Standard, not certified
–
Reduced energy consumption by 130 mill. Liter
oil-equivalent/year
–
Higher value of buildings from 3% (condominiums) to
6% (single family houses)
–
Awaken the economical interest of the industry in
energy efficient products
–
Set-up the largest Swiss training organization in
building sector
–
Increased building industry by 8‘500 jobs (3%)
The Reasons behind the MINERGIE
®
Success
–
Clear, simple and voluntary building standard
–
Broad national, state and local support in political and
business circles, as also in trade and professional
associations
–
First of all: comfort in the home and at workplace;
secondly, lower energy bills
–
A clear and consistent brand strategy
–
State application and certification
–
Professional networking
